FAQs About Leak Detection
How fast can you respond to a leak?
Quickly, active leaks are a priority. We offer prompt scheduling for San Diego and the surrounding area.
What is a slab leak?
A slab leak is a pipe leak beneath your concrete foundation. They're common in older San Diego homes and need prompt repair to prevent costly structural and flooring damage.
Can you find a leak without tearing up my home?
Yes. We use electronic and acoustic detection to locate leaks precisely, so repairs are targeted instead of destructive.
How do I know if I have a hidden leak?
Unexplained high water bills, warm spots on the floor, the sound of running water, mold, or a meter that moves when everything's off are all signs of a hidden leak.
